Yeah using AI to do a first stage pass seems to work well. I did something similar with Nano Banana: https://github.com/c-jiph/bitmap-to-gcode
I didn't actually end up playing with it too much but the problem I found was it's a hard to get a one-size-fits-all prompt. The AI generated images are usually okay but some features aren't great for a plotter or just don't look visually pleasing. It's still better than having to manually mess with the initial image.

Isn't the examples not very telling if you can't see the input too? Results look good, but I don't know what the input / what kind of preprocessing what done on it.

Very nice - I’ve struggled (and failed) with a similar approach previously.
FLUX.2 can run on a Mac - any thoughts on making this work on Mac? Needing a 24GB NVidia card is limiting…

That's a little bit to much for my trusty notebook...

Cool project! I tackled the same problem a few weeks ago to plot some nice Christmas cards. I will have a look at your skeletonization approach, because I was struggling with that.
In the end I just used potracer and was fine with having double lines for my cards: https://github.com/piebro/personal-plotting-util/blob/main/i...
